In this study, subjects with confirmed diagnosis of Multiple Sclerosis were randomized into one of two treatment arms. Subjects in the Lokomat arm trained on the Lokomat with a supervising physical therapist for 20-30 minutes/session 3 times/week. The Lokomat is a robotic exoskeleton which enables the subject to step on a moving treadmill. Subjects were suspended in a harness while in the Lokomat with full to partial body weight support as needed. After the training in the Lokomat, they practiced overground walking for 10 minutes.
